Description

Technical Field

[0001] The present invention relates to the technical field of feed processing, and specifically to a rapid cooling and shaping mechanism for a PE diaphragm used in energy storage batteries. Background Art

[0002] A PE diaphragm is a porous polymer film with polyethylene as the base material, usually single-layer or multi-layer, having high chemical stability and mechanical strength. It is widely used in energy storage batteries, especially in lithium-ion batteries. It is a key component in lithium-ion batteries, mainly used to isolate the positive and negative electrodes to prevent short circuits, and at the same time allow lithium ions to pass through to complete the charge and discharge process.

[0003] Currently, when most energy storage battery PE diaphragms are produced using the extrusion method, when polyethylene particles are heated and melted in an extruder and then extruded through a die to form a film, after the film is extruded, the extruded film is usually cooled by two cooling rollers. When the upper cooling roller is in use, since the cooling water accumulates below the cooling roller and cools the part where the cooling roller contacts the film, during the circulation of the cooling water, the cooling water accumulated in the upper layer will be replaced first. As a result, when the cooling water at the bottom contacts the PE diaphragm for a long time, the temperature of the cooling water will gradually rise, thus affecting the cooling efficiency. In view of the above problems, the inventor proposes a rapid cooling and shaping mechanism for a PE diaphragm used in energy storage batteries to solve the above problems. Summary of the Invention

[0038] By adopting the above technical solution, the second cooling roller 108 can cool the PE diaphragm.

[0039] The driving mechanism 2 includes a mounting plate 201. The side of the mounting plate 201 close to the extrusion device 5 is fixedly installed on the support frame 101 located on the right. A moving seat 202 is slidably installed inside the mounting plate 201. A connecting bar 203 is fixedly installed on the side of the moving seat 202 close to the support frame 101.

[0042] By adopting the above technical solution, the vertical rod 208 can drive the rotating rod 204 and the rotating rod 205 to rotate.

[0043] The circulation mechanism 3 includes a storage tank 301. The storage tank 301 is located below the two support frames 101, and the bottom ends of the two drain pipes 109 are fixedly connected to the storage tank 301. A circulation pump 302 is fixedly installed on the side of the storage tank 301 close to the air-cooling mechanism 4.

[0044] By adopting the above technical solution, the circulation pump 302 can transport the cooling water inside the storage tank 301.

[0045] The air-cooling mechanism 4 includes a housing 401. The housing 401 is located on the side of the support plate 101 away from the drain pipe 109. A cross plate 402 is fixedly installed inside the housing 401. A fan 403 is rotatably installed on the upper surface of the cross plate 402. A second motor 405 is fixedly installed at the bottom inside the cross plate 402, and the top end of the output shaft of the second motor 405 is fixedly connected to the fan 403.

[0046] By adopting the above technical solution, the second motor 405 can drive the fan 403 to rotate.

[0047] Two cooling pipes 406 are fixedly installed at the lower part inside the housing 401. One end of each of the two cooling pipes 406 is connected to the water outlet pipe of the circulation pump 302, and the other end is connected to the installation pipe 117 and one end of the first cooling roller 107 close to the housing 401. The cooling pipes 406 are rotatably connected to one end of the first cooling roller 107 close to the housing 401. Three transmission pipes 404 are fixedly installed at one end of the housing 401 close to the extrusion device 5, and the other ends of the three transmission pipes 404 are respectively connected to the second cold air box 104 and the two first cold air boxes 103.

[0048] By adopting the above technical solution, the cooling water can cool the air flow at the bottom of the housing 401.

[0049] Working principle: First, turn on the first motor 210 to drive the vertical rod 208 to rotate. By the rotation of the vertical rod 208, the sleeve 211 is driven to rotate. By the rotations of the sleeve 211 and the vertical rod 208 respectively, the two second bevel gears 209 are driven to rotate. By the rotations of the two second bevel gears 209, the two first bevel gears 206 are driven to rotate. By the rotations of the two first bevel gears 206 respectively, the rotating rod 204 and the rotating bar 205 are driven to rotate. By the rotations of the rotating rod 204 and the rotating bar 205 respectively, the first cooling roller 107 and the second cooling roller 108 are driven to rotate;

[0050] Next, turn on the circulation pump 302 to transport the cooling water inside the storage tank 301, and make it transported into the cooling pipe 406. The cooling pipe 406 cools down the air flow at the bottom of the outer shell 401. Then, turn on the second motor 405 to drive the fan 403 to rotate, and blow out the cold air flow at the bottom of the outer shell 401 through the rotation of the fan 403. At this time, the blown cold air flow is respectively transported into the second cold air box 104 and the two first cold air boxes 103 through the three transmission pipes 404. The PE diaphragm is cooled once by the two first cold air boxes 103, and the storage tank 301 is cooled by the second cold air box 104, so as to cool down the cooling water inside the storage tank 301;

[0051] Then, the cooling water is respectively transported into the installation pipe 117 and the first cooling roller 107 through the two cooling pipes 406. At this time, the cooling water is transported into the horizontal pipe 113 through the water inlet. At this time, the cooling water is sprayed out through the nozzles 114 on the outer surfaces of the horizontal pipe 113 and the installation pipe 117 to cool down the inner walls of the first cooling roller 107 and the second cooling roller 108 respectively. Thus, the PE diaphragm is cooled secondly through the contact between the first cooling roller 107, the second cooling roller 108 and the PE diaphragm;

[0052] Finally, during the rotation of the first cooling roller 107, the cooling water inside the partition area of the first cooling roller 107 enters the fixed pipe 110 through the slope and the drainage groove formed by the partition plate 111. At this time, the cooling water is discharged from the fixed pipe 110 through the slope of the hexahedron column 112, and enters the storage tank 301 through the drainage port and the drainage pipe 109 of the first cooling roller 107. At this time, since the drainage speed is higher than the water inlet speed, the cooling water inside the partition area is replaced as a whole, avoiding the phenomenon that the cooling water heats up due to long-term cooling.

[0053] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
